alpha2-macroglobulin, MAM, A2M, alpha2M
Alpha-2-macroglobulin is a protease inhibitor and cytokine transporter. It inhibits many proteases, including trypsin, thrombin and collagenase. A2M is implicated in Alzheimer disease (AD) due to its ability to mediate the clearance and degradation of A-beta, the major component of beta-amyloid deposits.

Papers on alpha2-macroglobulin
Krediet et al., Amsterdam, Netherlands. In Perit Dial Int, 13 Dec 2014
However, the frequent peritonitis group had lower peritoneal protein clearances compared to the no peritonitis group, resulting in lower dialysate concentrations of proteins: albumin 196.5mg/L vs 372.5 mg/L, IgG 36.4 mg/L vs 65.0 mg/L, and α-2-macroglobulin (A2M) 1.9 mg/L vs 3.6 mg/L, p<0.01.
Mitochondria-associated membrane formation in hormone-stimulated Leydig cell steroidogenesis: Role of ATAD3.
Papadopoulos et al., Montréal, Canada. In Endocrinology, 06 Dec 2014
Taken together, these results demonstrate that the hormone-induced, ATAD3-mediated, MAM formation participates in the optimal transfer of cholesterol from the ER into mitochondria for steroidogenesis.
Dynamic and extensive metabolic state-dependent regulation of cytokine expression and circulating levels.
Wong et al., Hopkins, United States. In Am J Physiol Regul Integr Comp Physiol, 15 Nov 2014
In the context of chronic high-fat feeding, circulating levels of CXCL1, SAA3, TIMP-1, AGP, and A2M were increased, whereas IL-12p40, CCL4, sCD30, sRAGE, CCL12, CCL20, IL-16, IL-22, and haptoglobin were decreased relative to mice fed a control low-fat diet.
Alpha-2-macroglobulin as a radioprotective agent: a review.
Fang et al., Guangzhou, China. In Chin J Cancer Res, 31 Oct 2014
Recent studies have shown that alpha-2-macroglobulin (α2M) possesses radioprotective effects.
Mitochondrial import and degradation of amyloid-β peptide.
Glaser et al., Stockholm, Sweden. In Biochim Biophys Acta, Jul 2014
The γ-secretase complex was found in mitochondria-associated endoplasmic reticulum membranes (MAM) suggesting that this could be a potential site of Aβ production, from which Aβ is further transported into the mitochondria.
MAM (mitochondria-associated membranes) in mammalian cells: lipids and beyond.
Vance, Edmonton, Canada. In Biochim Biophys Acta, May 2014
One mechanism by which communication between the endoplasmic reticulum (ER) and mitochondria is achieved is by close juxtaposition between these organelles via mitochondria-associated membranes (MAM).
Bcl-2 family in inter-organelle modulation of calcium signaling; roles in bioenergetics and cell survival.
Betenbaugh et al., In J Bioenerg Biomembr, Feb 2014
Type 1 IP3Rs reside at the bulk ER to coordinate cytosolic Ca2+ signals, while type 3 IP3Rs reside at mitochondria-associated ER membrane (MAM) to facilitate mitochondrial Ca2+ uptake.
Animal models of brain maldevelopment induced by cycad plant genotoxins.
Spencer et al., Oregon, United States. In Birth Defects Res C Embryo Today, Dec 2013
The neuropathology of amyotrophic lateral sclerosis/parkinsonism-dementia complex includes features suggestive of brain maldevelopment, an experimentally proven property of cycasin attributable to the genotoxic action of its aglycone methylazoxymethanol (MAM).
Discovery of prognostic factors for diagnosis and treatment of epithelial-derived ovarian cancer from laying hens.
Song et al., Seoul, South Korea. In J Cancer Prev, Sep 2013
Therefore, we showed in the review: 1) characterization and classification of EOC; 2) chicken models for EOC; 3) relationship estrogen with EOC; 4) candidate prognostic factors for EOC including serpin peptidase inhibior, clade B (ovalbumin), member 3 (SERPINB3), SERPINB11, gallicin 11 (GAL11), secreted phosphoprotein 1 (SPP1) and alpha 2 macroglobulin (A2M) in normal and cancerous ovaries of laying hens; 5) biological roles of microRNAs in development of EOC.
Diet1 functions in the FGF15/19 enterohepatic signaling axis to modulate bile acid and lipid levels.
Reue et al., Los Angeles, United States. In Cell Metab, Jul 2013
Diet1 encodes a 236 kD protein consisting of tandem low-density lipoprotein receptor and MAM (meprin-A5-protein tyrosine phosphatase mu) domains and is expressed in the enterocytes of the small intestine.
Clinicopathological characteristics of androgen-dependent advanced prostate cancer patients with α2-macroglobulin deficiency.
Akahoshi et al., Sagamihara, Japan. In Int J Oncol, 2012
alpha-2-macroglobulin (a2M) deficiency develops from catabolism of a2M in androgen-dependent advanced prostate cancer patients
Diagnostic value of multiple biomarker panel for prediction of significant fibrosis in chronic hepatitis C.
Kim et al., Pusan, South Korea. In Clin Biochem, 2011
We observed that the most informative biomarkers for predicting significant liver fibrosis in chronic hepatitis C patients were blood levels of alpha2-macroglobulin and hyaluronic acid
Expression, purification and structural analysis of recombinant rBdh-2His₆, a spermadhesin from buck (Capra hircus) seminal plasma.
Cavada et al., Fortaleza, Brazil. In Reprod Fertil Dev, 2011
investigation of secondary structure and thermal stability of recombinant bodhesin 2, a spermadhesin from seminal plasma
Requirements for mediator complex subunits distinguish three classes of notch target genes at the Drosophila wing margin.
Treisman et al., New York City, United States. In Dev Dyn, 2011
Genes activated by Notch signaling at the dorsal-ventral boundary of wing disc fall into classes affected differently by the loss of kinase module subunits. The distinctions do not result from different requirements for Groucho.
Relationship between production of acute-phase proteins and strength of inflammatory stimulation in rats.
Yamamoto et al., Sagamihara, Japan. In Lab Anim, 2011
Peak serum levels of alpha(2)-macroglobulin and alpha(1)-acid glycoprotein injected at 0.05 mL/rat were significantly lower than those at 0.2 or 0.4 mL/rat. No significant differences were observed for peak serum levels at 0.2 and 0.4 mL/rat.
Sigma-1 receptor chaperones at the ER-mitochondrion interface regulate Ca(2+) signaling and cell survival.
Su et al., Baltimore, United States. In Cell, 2007
The ER supplies Ca(2+) directly to mitochondria via inositol 1,4,5-trisphosphate receptors (IP3Rs) at close contacts between the two organelles referred to as mitochondrion-associated ER membrane (MAM).
The Notch transcription activation complex makes its move.
Kopan et al., Baltimore, United States. In Cell, 2006
These structures show that the ANK domain of Notch is an integral part of the transcription complex and supports MAM binding, whereas the RAM domain may trigger allosteric changes in the structure needed for the derepression of transcription.
Structures of complement component C3 provide insights into the function and evolution of immunity.
Gros et al., Utrecht, Netherlands. In Nature, 2005
The structures reveal thirteen domains, nine of which were unpredicted, and suggest that the proteins of the alpha2-macroglobulin family evolved from a core of eight homologous domains.

It shows substantial structural and functional similarities, including the highly conserved thioester motif, to both a central component of mammalian complement system, factor C3, and to a pan-protease inhibitor, alpha2-macroglobulin.
